Ice Loss In West Antarctica Is Speeding Up 422

An anonymous reader writes: A new study just published on Antarctic ice loss by Christopher Harig and Frederik Simons of Princeton confirm West Antarctica is losing mass fast. The study used satellite measurements to determine the rate of mass loss. The lead author of the study told The Guardian: "It is very important that we continue long term monitoring of how mass changes in ice sheets. For West Antarctica in particular this is important because of how it is thought to be more unstable, where the feedbacks can cause more and more ice loss from the land over time. These strong regional accelerations that we see are very robustly measured and imply that Antarctica may become a major contributor to sea level rise in the near future. This increase in the mass loss rate, in ten years, accelerations like that show that things are beginning to change on human time scales."

    Of course, we're not going to do anything about the problem. Of course not.

      why not?

      how much does the sea rise if the entire west antarctic melts?

        "If the entire West Antarctic Ice Sheet were to melt, this would contribute 4.8 m (16 ft) to global sea level."

        Obviously, even if this were to happen, it would take a considerable amount of time.

        • I think it could take a very long time, but then again it could take far less than we would expect. The Larsen B ice shelf disintegrated in something like 3 weeks. Scientists at the time knew it was unstable and in trouble but nobody thought that much ice could breakup and melt so fast.

          Unfortunately, it's not just West Antarctica. There are areas on the eastern side that are of great concern, the rate of ice loss is up over 70% in 10 yrs and then there's Greenland and the overwhelming majority of land-based glaciers that are also melting.

          Yes, it'll all take time but with every passing decade it seems to be speeding up.

      Well, I used to be a denialist that thought there were nothing needed to do, because there was no problem.

      But now, I'm convinced: there is a climate change and it is pushed forward by humankind.

      Unfortunately, it's too late to avoid it, so I'll do nothing either.

      Funnily many of the climate change deniers also own beachfront property. Perhaps it will be slightly harder to deny when their beach front property is under 10 feet of water.

      You probably have a really small car.

      Climate change is normal - it's happened throughout history.

      Warm weather will be nice - I'll save money on heating. Are you a shill for power companies?

      The "ice" has melted before - it was good (comeonin). Dinosaurs aren't going to come back... and there won't be any volcanoes where I live.

      I've got a multi-billion dollar plan to stop global warming if it really bothers you - it does require a hell of a lot of energy and toxic by-products (but we've proved overheating the

      What exactly is a "climate change denier"? Is that someone who denies that the climate changes? Would you be so kind as to point to a specific example of someone who has actually said the climate hasn't changed, isn't changing and won't change? I certainly don't know of anyone who is that stupid.

      (Although, it does seem that some people think the climate shouldn't change and that, because it is changing, that's a Bad Thing. But those aren't the skeptics.)

      These are satellite measurements, so probably zero.

    Miami Beach Florida is already having rising seas flooding in some streets. I ask you to consider the massive economic impact on the entire nation that the loss of Miami Beach would create. The investments in Miami Beach structures and land is enormous. A loss of Miami Beach would be enough to wipe out numerous insurance companies and banks with perhaps enough losses to totally crash the US economy. Consider that even way back in 1950 land on Miami Beach was valued in the hundreds of dollars per square foot. Most of Miami Beach is about 30 inches above sea level. A high tide is already enough to create some flooding. The area is also prone to hurricanes. Storm surges can reach 20 feet. Even a very minor storm could easily have a five foot surge. But storms also have huge waves so you might have a 30 ft. wave on top of the surge water. Plainly said a decent storm with rising seas could erase Miami Beach from the face of the Earth. Miami is only one example. But rising seas are a much more immediate threat to all of us than what we see in the news media. We can have a hell of a price to pay right now. For climate deniers we did not face this much of an issue fifty years ago. Right now people really should be very afraid.
